Hilbert curve fractal, order 4, drawn as a line
Hilbert curve fractal, order 4. The preview is the SVG file itself.

One line that visits every cell of a 16 by 16 grid and never crosses itself. Each order is four half-size copies of the last, the first and last turned to face inwards, joined by three steps. 255 steps, line half a step wide.

How fine is it at your size?

Scaling a design scales its finest detail too. Here is this one at seven sizes, from 1 to 12 inches on its longer side, with how many copies fit a 12 × 12 inch sheet or mat.

The narrowest part is the finest detail in the pattern. Below about half a millimetre it is too small to cut and may fill in when printed. How to open the file in Cricut, Silhouette and laser software.
